Abstract
A method for retrieving in-situ building information based on visual gaze is disclosed, including: extracting and optimizing a building information model; obtaining gaze data; aligning the BIM model with a physical structure of the building through a spatial anchors technology; and wearing MR device for on-site building information retrieval. Based on MR technology, the present invention provides a visual gaze retrieval method for building information with real building components as the carrier. The MR technology is used to link and bind the digital information of building components with the physical entities of building components; the eye tracking technology is used to perform the visual information retrieval of building components. Users can rapidly obtain relevant building information, such as material properties and design parameters, by gazing at real building components, which improves the efficiency of on-site work and brings significant improvement and convenience to the construction industry.
